Management of poor-grade subarachnoid haemorrhage: a self-fulfilling prophecy of good outcome?

Outcomes following acute poor-grade aneurysmal subarachnoid bleed - Is early definitive treatment better than delayed management?

BACKGROUND/OBJECTIVE

Patients with poor-grade subarachnoid bleed (World Federation of Neurosurgical Societies grades 4-5) often improve their neurocognitive function months after their ictus. However, it is essential to explore the timing of intervention and its impact on long-term outcome. We compared the long-term outcomes between immediate management within 24 h and delayed management after 24 h in patients following poor-grade subarachnoid bleed.

METHODS

This was a retrospective population-based study, including patients with poor-grade subarachnoid bleed who received definitive management between 1 January 2011 and 31 December 2016 in a large tertiary neurocritical care unit. The primary outcome was adjusted odds ratio of favourable outcome (Glasgow Outcome Scale 4-5) for survivors at 12 months following discharge, as measured by the Glasgow Outcome Scale. The secondary outcomes included adjusted odds ratio of a favourable outcome at discharge, 3 months and 6 months following discharge and survival rate at 28 days, 3 months, 6 months and 12 months following haemorrhage.

RESULTS

A total of 111 patients were included in this study: 53 (48%) received immediate management and 58 (52%) received delayed management. The mean time delay from referral to intervention was 14.9 ± 5.8 h in immediate management patients, compared to 79.6 ± 106.1 h in delayed management patients. At 12 months following discharge, the adjusted odds ratio for favourable outcome in immediate management versus delayed management patients was 0.96 (confidence interval (CI) = 0.17, 5.39; p = 0.961). At hospital discharge, 3 months and 6 months, the adjusted odds ratio for favourable outcome was 3.85 (CI = 1.38, 10.73; p = 0.010), 1.04 (CI = 0.22, 5.00; p = 0.956) and 0.98 (CI = 0.21, 4.58; p = 0.982), respectively. There were no differences in survival rate between the groups at 28 days, 3 months, 6 months and 12 months (71.7% in immediate management group vs. 82.8% in delayed management group at 12 months, p = 0.163).

CONCLUSIONS

Immediate management and delayed management after poor-grade subarachnoid bleed are associated with similar morbidity and mortality at 12 months. Therefore, delaying intervention in poor-grade patients may be a reasonable approach, especially if time is needed to plan the procedure or stabilise the patient adequately.

Intersection of prognosis and palliation in neurocritical care

PURPOSE OF REVIEW

Difficult discussions regarding end-of-life care are common in neurocritical care. Because of a patient's neurological impairment, decisions regarding continuing or limiting aggressive care must often be made by patients' families in conjunction with medical providers. This review provides perspective on three major aspects of this circumstance: prognostication, family-physician discussions, and determination of death (specifically as it impacts on organ donation).

RECENT FINDINGS

Numerous studies have now demonstrated that prediction models developed from populations of brain-injured patients may be misleading when applied to individual patients. Early care limitations may lead to the self-fulfilling prophecy of poor outcomes because of care decisions rather than disease course. A shared decision-making approach that emphasizes transmission of information and trust between families and medical providers is ethically appropriate in severely brain-injured patients and as part of the transition to end-of-life palliative care. Standard definitions of death by neurological criteria exist, although worldwide variation and the relationship to organ donation make this complex.

SUMMARY

End-of-life care in patients with severe brain injuries is common and represents a complex intersection of prognostication, family communication, and decision-making. Skills to optimize this should be emphasized in neurocritical care providers.
